Speaker wire is often the culprit behind crackly speakers.
Speakers are devices that translate the signals sent from an audio source (like a CD player or TV) into audible sound waves. Occasionally, when there are some problems in the connection between the speakers and the audio device, or the speakers are incorrectly calibrated, there will be some static or crackly sounds coming from the speakers. Correcting the problem may be as simple as fine-tuning the control knobs or cleaning the speaker wires.
Instructions
1. Listen to the audio and try to isolate when the speakers are making the crackly noises. Is it constant throughout the audio? When you adjust the frequency settings? This will determine the correct course of action when dealing with the crackly sounds.
2. Adjust some of the frequency knobs on the audio tuner. Use subtle changes at first. Some older audio tuners occasionally sound crackly when the knobs are placed in between settings
3. Look at the wiring, both in the back of the speakers (black and red input jacks known as speaker terminals) and in the audio device. Remove the wire from the respective devices.
